In this situation, biweekly represents a period. Its meaning, occurring every two weeks, shows biweekly as an adjective. An adjective is a term that describes a noun’s feature.

The difference between semiweekly and biweekly is the frequency of an event. If you are getting paid twice a month, that means your salary is set to biweekly. When you go grocery shopping twice a week, then you have a semiweekly setup.
